原子干涉技术在惯性领域中的应用

惯性技术因其强自主性、不依赖外界信号、适应全天候等特性在导航领域备受关注，为了提升惯性导航的精度，数十年来人们在如何提高惯性传感器性能方面进行了大量的攻关工作并研制出了多种基于不同原理的惯性传感器。得益于量子效应，原子传感器能在诸如时间、加速度、转动、磁场等领域提供比现有技术更高的测量灵敏度、精度和速度。通过研制基于原子干涉技术的高精度原子惯性器件，实现重力/重力梯度数据实时补偿匹配的量子导航将是新一代高精准军用惯性导航的首选。本文简要介绍了以物质波干涉为基础的原子干涉惯性器件的原理，回顾了以原子重力仪、原子干涉陀螺为主的技术发展历程及现状，并结合我国目前在该领域的发展态势，表达了对我国原子惯性设备实装应用的迫切性。

Atomic Interference-based Quantum Technology and Its Application for Inertial Navigation

Inertial navigation system is an autonomous system with good concealment, which is not dependent on any external information, nor radiates energy to external space, making it applicable in airspace, sea, or underground. Over the course of the last few decades, numerous efforts have been devoted to improving the performance of inertial navigation and various kinds of inertial sensors have been developed. By harnessing quantum effects, atomic sensors can offer higher sensitivity, accuracy and speed of use than current technologies, particularly for timing, acceleration, rotation and magnetic. The quantum navigation, integrated with atomic gyroscope, atomic accelerometer and real-time gravity/gradient matching, paves a new way to the next generation inertial technology. In this paper, we make a brief introduction about the atomic inertial technology based on atomic interferometry. By reviewing the developments of atomic interferometer gyroscope and atomic gravimeter, we claim the future of atomic inertial sensors is bright and it is in urgent need to devote self-developed atomic inertial devices to practical field applications.
